Description

Technical Field

[0001] This utility model relates to the field of segment mold technology, specifically to a segment mold size inspection device. Background Technology

[0002] Segment molds are specialized precast concrete molds used for producing tunnel segments. Their geometric parameters need to be customized according to the specific tunnel project. They are widely used in subways, cross-sea tunnels, and other fields. The geometric dimensions and shape of tunnel segments are determined by the geometry and characteristics of the tunnel. Each tunnel is different, and the segments of each tunnel are also different, so the segment molds are naturally different. If the dimensions of the segment mold are to be inspected, a segment needs to be produced using the mold first, and the dimensions of this segment need to be inspected before it can be determined whether the dimensions of the mold are qualified.

[0003] As indicated by announcement number CN222652117U, a segment size inspection device is provided. This device includes an inspection base; a drive motor bolted to one side of the inspection base; two sets of fixing rods, which are located inside the inspection base; and a segment body. It has the advantages of being easy to use, having a wide range of applications, and enabling rapid inspection, which greatly improves the efficiency of measuring and inspecting the curvature of the segment body.

[0004] The aforementioned device uses several trigger heads to contact the bottom of the tube segment and measures the bending degree of the tube segment by the displacement distance of the trigger heads. However, the trigger heads are movable mechanisms and will return to their original positions under the action of springs after the tube segment is removed. This makes it inconvenient to limit the position of the trigger heads, resulting in difficulty in accurately judging whether there is an error in the position of the trigger heads. Utility Model Content

[0005] The purpose of this invention is to provide a tube sheet mold size inspection device to solve the problem mentioned in the background art that the trigger head is a movable mechanism, which returns to its original position under the action of a spring after the tube sheet is removed, making it inconvenient to limit the trigger head and resulting in difficulty in accurately judging whether there is an error in the position of the trigger head.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a segment mold size inspection device, including a base plate;

An electric push rod is provided on the outer side of the upright frame, and the electric push rod is connected to the connecting plate through connecting rods.

[0011] Preferably, a cylinder is provided at the upper center of the base plate, the bottom of the arc plate is connected to the base frame via a bracket, and the cylinder is connected to the bottom of the base frame via a connecting rod at the upper end.

[0012] Preferably, a clamp is provided above the base plate, and two sets of clamps are provided and symmetrically distributed at both ends of the arc-shaped plate.

A motor is provided at one end of the bidirectional screw, and the motor is located on the outside of the base plate. Slider blocks are symmetrically arranged on both sides inside the sliding groove, and the sliders are threadedly connected to the bidirectional screw through threaded holes on the surface. A support rod is provided at the upper end of the slider, and the support rod is connected to a clamp at a corresponding position.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting an arc plate, the tube segment is placed on the fixture. The arc plate is driven to rise by the cylinder, so that the movable plate is on the bottom of the tube segment. Several movable plates on the surface of the arc plate descend to different heights according to the arc shape of the bottom of the arc plate. Then, the upper and lower pressure plates are driven by the electric push rod on one side to clamp the movable plates at different positions and limit the position of the movable plates. When the tube segment is picked up, the movable plate is still in the current position. The curvature of the tube segment can be detected by the scale strip on the side plate of the movable plate, so as to determine whether the size of the tube segment mold is qualified.

[0016] (2) By setting a limiting block inside the locking groove and setting a limiting groove on the surface of the movable plate, the stability of the movable plate is improved by the limiting block being locked in the limiting groove. A spring is set at the upper end of the limiting block. When the pressure plate is released, the spring can be used to raise several movable plates to their original positions. The spring can also keep the curved plate attached to the bottom of the curved plate when the movable plate contacts the bottom of the curved plate, thereby improving the accuracy of the inspection.
